PSI Solver (SIwave) ignores parts

    • Harri Pankratz

      Hello, tried to run PSI solver for AC currents computation on a PCB board imported from Cadence.
      The solver reported a list of ignored parts:


      Running the SIwave solver (frequency sweeps) causes no problems.
      Pads/pins seem to be in order.

      Thanks in advance for any suggestions.

      Hi Harri,

      Please check if the nets are imported as required.

      Best regards,

      Hello Praneeth,

      thanks for the tip, it looks like the corresponding net (in pictures below: "_VB") is not included and all connected parts are dropped as consequence. I am just wondering why the net is dropped.
      The resistor "RLC_D210" is connecting the net "_VB" to the net "_VB_RP" (pictures below):

       

      Best regards

      Hi Harri,

      The nets might have been dropped due to the warning that some parts are dropped which you informed in the initial post. 

      To troubleshoot the issue, please raise a service ticket in the customer portal if you have access as this cannot be done in this forum.

      Best regards,
      Praneeth.
